Elevated temperatures take a big toll on gas turbine components risking cracks, corrosion, wall thickness, and material condition. Repair enhancements can extend a part’s life by slowing its degradation and pushing out its usable service life. Operators can see significant savings by opting for lower-cost repaired spares instead of new parts as demonstrated in the following case studies.

On July 29, 1949, at 2:15 p.m., General Electric’s (GE’s) first gas turbine at the Belle Isle Station in Oklahoma City began delivering power to Oklahoma Gas and Electric Co.’s distribution system. The 3.5-MW GE Frame 3 machine reportedly had an efficiency of about 17%. Since the Belle Isle machine (Figure 1) started up seventy […]

NuScale Power, Rolls-Royce, and China National Nuclear Corp. (CNNC)—three companies working on different small modular reactor (SMR) technology—recently announced positive developments for their respective designs. NRC Makes Progress on NuScale Design Review Portland, Oregon-based NuScale said on July 22 that the U.S. Nuclear Regulatory Commission (NRC) completed the second and third phases of its SMR […]

BHP and Mitsubishi Development Pty (MDP) in late June signed a memorandum of understanding for joint research, development, and deployment of greenhouse gas emissions reduction technologies in several countries, including projects with battery storage, solar, and carbon capture and storage (CCS). The agreement, signed in Tokyo, Japan, on June 20, also calls for research into […]

Nuclear power advocates suggest there are many benefits associated with nuclear energy. They point to high-paying jobs; billions of dollars in economic activity for plant-hosting communities; and secure, reliable, baseload electricity. But the most-important benefit of nuclear power may be that it emits no greenhouse gases, and therefore does not contribute to climate change. According […]

Tokyo Electric Power Co. (TEPCO) on July 24 said it will decommission its Fukushima Daini nuclear station. The plant is located just south of the larger Fukushima Daiichi plant, site of a meltdown in March 2011 after an earthquake and tsunami heavily damaged the Daiichi facility. The four reactors at Daini automatically shut down after […]

Venture capital investments in battery storage companies and projects rose significantly year-over-year through the first six months of 2019, according to a report from Mercom Capital Group. That level of activity is consistent with the growth in energy storage noted by speakers on July 24 at the Storage Week Plus conference in San Francisco, California. […]

Ohio’s Gov. Mike DeWine (R) on July 23 quickly signed a controversial nuclear subsidy bill that narrowly passed the state’s House of Representatives on Tuesday, making Ohio the fifth state in the nation to prop up nuclear power.  Lawmakers passed H.B. 6 with a 51–38 vote Tuesday. The bill passed the state Senate on July […]

GE Renewable Energy’s mammoth offshore wind 12-MW Haliade-X  turbine is on track for an accelerated commercial launch in 2021, the company said as it unveiled the turbine’s first manufactured components on July 22. Haliade-X features a 220-meter (m) rotor and a 107-m blade designed by GE subsidiary LM Wind Power. The turbine design also includes […]

JEA, the electric utility in Jacksonville, Florida, has been decommissioning the St. Johns River Power Park over the past year. A third implosion as part of the decommissioning occurred July 19, as a 640-foot-tall stack and two steam generating boilers were demolished. Friday’s work followed similar implosions in June 2018, when the plant’s two, 464-foot-tall […]
